Voici le témoignage de Aitor E.
I've been happily learning English with the Gymglish app. The best aspect of it was the rate of the lessons: I could learn when I decided to. It was very important for me to finish a lesson before receiving the next one. So lessons couldn't accumulate. Also, I would say 30 minutes were enough to finish each lesson, more or less. Vocabulary and listening have been the best aspects for me, but I would have liked more speaking and writing. Thank you very much.
